This piggyback kydex carrier is hand made of moulded kydex. It holds the TOPS emergency 3 rod fire starter. It has 2 mounting holes, the top hole is premade and the second hole is left for you to make. This way it will fit your own sheath. The piggyback comes with 2 mounting screws and it does fit most manufacturer's kydex sheaths. The piggyback setup holds close to the body of the sheath and the firestarter can be pulled out for use fairly easily.
